white paint turning yellow

hello

A friend of mine has painted his interior doors white about one year ago.
Last week he sad that from a couple of doors one side turned yellow.
I went to have a look at it this morning and found out that 3 doors plus the frames have the problem. Al of them are doors that give acces to build in closets, and it is the "inside" of the door and frame thats turning yellow.

The paint he used is the same paint he used for the rest of the house, and the rest looks fine. Hot/ cold can't be the problem because he has central heating and an AC wich he uses. No moisture problems either.
I know that paint can change color due to sunlight, can the lack of sunlight be the problem??

Yep i concur, Oil paint will yellow in dark places at a much quicker rate than where sunlight hits. I was in a house a couple of months ago that we ran oil in (stopped running oil a couple of years ago) and the trim looked great. Yet if i would of opened the closet door it no doubt would of been yellowed.
We used to have them shoot 2black at the paint store to slow the yellowing.
So closets, baths, anywhere that does not get sunlight will yellow.

I mean that we had the paintstore shoot a little bit of black in the bright white. It did not take from the color at all. 2black is just that. These days we are running manor hall high gloss waterborn, and we are going L2 which is 2shots of brown. It just gives it a bit more body to the paint for better coverage. Some bright whites tend to be a bit transparent.

Hi there,

I'm not certain abiut the sunlight and/or mix in the paint.
I painted my trim and doors on all of the bedrooms (bedroom, bath, closet) as well as halway closets. I noticed, the frame is not yellow but the door is. Any suggestions as of why aside from sunlight or paint?

It is the paint. Bet it was an oil finish , right? I have had times that you couldn't touch up an oil enamel 3 months after applied- out of the same can.

It is the downside of oil , and one of the selling points of the newer "non- yellowing" waterbornes.

Well, the paint is new, yes and it's oil base. It's bright white and we painted over the old oil based paint on the door, door frame (jam) and baseboard trim. The only place turned yellow are the doors! So that is still the paint? If so, how do one mitigate the issue?
